USB loader not working

Hi,

okay, so I went to play on the wii this morning, and when i went onto USB Loader, and went into start, it tried to load and then came up black with white letters and numbers, which I was unable to read. This has happened before, so we took it to the place where we got our wii chipped, and they did fix it, but it cost over $100... Is there any way I can fix it at home, or fix it with out payment?
Thanks,
Chessnutz.
